摘　　要：在湘潭锰矿区及其外围的地质灾害调查过程中,研究了已有地质工作成果,分析了区内塌陷现状,利用多种地球物理探测技术对其进行了快速有效的评价。首先介绍了区内地质、地层、构造等特征,在研究了区内已有成果的情况下对目前的塌陷进行了划区,根据不同典型区域设计了不同地球物理方法进行探测、数据处理和分析;钻探结果证实了对区内塌陷的评价。调查研究表明:本次探测效果明显,区内塌陷可分为4类,其引起的地质灾害具有独特的特点。勘查结果为后期治理提供了基础资料。In the process of geological disaster investigation in the Xiangtan manganese ore district and its surrounding areas,the geological achievements were studied,the present situation of collapse in the area was analyzed,and the geophysical detection technology was used to make evaluation quickly and effectively. Firstly,the characteristics of geological,strata and structure in the area were described. Secondly,the existing subsidence area was studied and the geophysical methods were designed according to different typical areas. Finally,according to the drilling results,the evaluation of the collapse in the area was realized. The research results show that the detection effect is obvious,the regional collapse can be divided into four categories,and the geological disasters caused by it have unique characteristics. The results obtained by the authors provide the basic data for later treatment.
